Application filed June 20, 1910. Serial No. 567,955.

To all whom it may concern Be it known that I, BENJAMIN PUTNAM PoLLooK, a citizen of the United States, residing at Appleton, in the county of Outagamie, in the State of WVisconsin, have invented new and useful Improvements in Hotel-Ranges, of which the following is a specification.

This invention relates to hotel ranges, and has for its object to provide a hotel range of improved construction and arrangement.

Another object is to provide a hotel range with a central fire pot and large top of annular form, whereby a great number of utensils may be placed thereon at one and the same time, and all subject to the same, or practically the same degree of heat.

Another object is to provide a hotel range having an abnormally large top, and an oven with draft controlling means whereby the products of combustion may be directed to all parts of the top and oven so as to give uniform heat to said parts.

Other objects and advantages will appear in the course of this specification, and with all of said objects and advantages in view this invention consists in the several novel features hereinafter described and claimed.

The invention is illustrated in the draw ings furnished herewith, in which Figure 1 is a plan of a hotel range embodying one form of the present invention, Fig. 2 is a view partly in end elevation and partly in central vertical cross section taken on the line 22 of Fig. 1, Fig. 3 is a view partly in side elevation and partly in central longitudinal section taken on the line 38 of Fig. 1, Fig. 4 is a plan of a damper frame and conoidal division wall, Fig. 5 is a detail side elevation of said wall, showing certain dampers, Fig. 6, is a view partly in horizontal section through the range, showing its fire box in plan, Fig. 7 is a detail horizontal section taken on line 77, Fig. 3, and Fig. 8, is a detail, vertical section taken on line 8-8, Fig. 1.

Referring to said drawings, A designates the base of the range which is preferably of rectangular form, as shown, and at its top said base is provided with a conoidal wall Q, at the upper edge of which is an annular plate or ring C, which forms the top of the stove. The ring C, is formed with a large number of openings 1*, grouped around the ring and preferably spaced equidistant Specification of Letters Patent.

from its center; said openings are arranged Patented Feb. 10, 1914.

to be covered with the usual lids or griddles R. Within the base A, is supported a firebox 0, here shown as of circular form and containing grate bars 7), a draft passage 00, extends from openings in the side wall of the base A, and leads into the fire box below the grate bars. Above said fire box is an inverted dome shaped wall D, which projects down from the inner margin of the ring O, in the form of a conoidal wall al preferably arranged parallel With the conoidal wall Q, and having at its lower end a concavo convex central portion 0Z Between the outer wall Q, and inner wall D, is a conoidal division wall or lining f, which is shown as supported from the wall Q, by means of struts f and said division wall or lining acts to divide the annular space be tween the outer wall Q, and inner wall D, into two passageways the one leading from the fire box up toward the ring C, and the other back from the ring to the base A. Said passages being annular in form, and the ascending passage communicating directly with the fire box, the hot gases, arising fro-1n the burning coals, pass upward to all parts of the ring C, whereby the entire ring, with the lids thereon, may be uniformly heated throughout.

Extending upward from the division wall or lining at a point near its lower end is an annular damper frame 6, which as shown in Figs. 4, and 5, tapers upward slightly and is formed with a large number of openings 6 through which the gases may pass from the fire box to the ascending passageway. Dampers P, are provided, one for each opening 6 in the damper frame and said dampers may be swung up against the damper frame 6, to close the openings therethrough when it is desired to change the course of the products of combustion. By this arrangement the dampers may be so manipulated as to direct the products of combustion toward any side of the annular space, or all of them may be opened so as to permit the gases to pass through the whole of the annular space, or all of the dampers may be closed, thereby shutting off said annular space from the fire box. The division wall or lining f, is provided at its lower end immediately above the fire box, with a set of openings, adapted to be closed by dampers m, rotatively mounted on the outside of a neck m of the division wall or lining m, whereby the hot gases and products of combustion may be permitted to escape through said openings and into the chamber surrounding the fire box instead of passing up through the annular space at the top of the stove.

An even g, is provided in the base A, and said even opens out through the ends of the base and is closed by doors The oven has a top wall and a bottom wall 9*, and said top wall is shown as supporting the fire box 0. The space within the base A, above the top wall 9 of the oven may be considered as a smoke passage a The walls 9 of said oven are spaced from the walls (R, of the base A, to leave passageways a, therebetween for the circulation of products of combustion from the firebox to the smoke flue. In the form shown, the bottom wall of the oven and the bottom wall of the base are spaced apart so as to permit the gases to pass underneath the oven, and a longitudinally extending flue i, is provided between said bottoms, said flue having openings h, in its sides through which the gases may enter the flue. Said flue connects with the smoke flue 7', through a transverse fine 2' at one end of the stove and said smoke fine is provided with an. opening a leading to the smoke passage a in the base and said opening is arranged to be closed by a damper 70. When said damper is thrown open, the gases may pass from smoke passage a in the base out through the opening a between said smoke passageway a and smoke flue j, instead of passing down around the oven, but by closing the damper 73', the gases are caused to circulate around the oven, through the flue 2', and out through the smoke flue The arrows in Figs. 2, 3 and 7 indicate the course of the products of combustion from the fire box to the smoke flue j when the dampers 7c and m are closed and the dampers, P, open; in other words the products of combustion pass up from the fire box, through the openings 6 in the damper frame a, up over the lining f, down between said lining and wall Q, down througl'i the smoke passage (4, down the passages, (:4 under the oven, through the holes 72,, in the flue 2', thence through said fine 2', and transverse flue 2' and up through the smoke flue j. One or more of the dampers P, may be closed to direct the products of combustion from the fire box toward any particular side of the range.

From the above it is perfectly obvious that all of the heat may be utilized to the best advantage and that a very large surface may be employed for receiving the cooking utensils, said surface receiving its heat from a comparatively small fire box, but being capable of uniform heat throughout.

I realize that various alterations and modifications of this device are possible without departing from the spirit of my invention, and I do not therefore desire to limit myself to the exact form of construction shown and described.

I claim as new and desire to secure by Letters Patent:

1. In a hotel range, a comparatively large ring having a plurality of covered openings therein, inner and outer conoidal walls extending down therefrom, a conoidal division wall arranged between said inner and outer conoidal walls to provide ascending and descending passageways, a base at the lower end of said outer conoidal wall, and a fire box supported in said base directly below said inner. conoidal wall and opening to said ascending passageway.

2. In a hotel range, an annular top having a plurality of openings arranged to be covered by lids, inner and outer conoidal walls projecting down therefrom, an intermediate division wall of conoidal form arranged to divide the space between the inner and outer conoidal walls into an ascending and a descending passageway, a rectangular base at the lower end of the outer conoidal wall, a the box centrally disposed in said base, and opening to said ascending passageway, an annular damper frame extending across said ascending passageway, and hav ing openings therein, and dampers for opening or closing said openings in the damper frame.

In a hotel range, an annular top having a plurality of spaced holes therein and lids for said holes, inner and outer conoidal walls projecting down from the margins of said top, a division wall of conoidal form between said inner and outer walls and forming ascending and descending passages in the space between said walls, an annular damper frame extending across said ascending passageway and having openings therein, dampers for opening and closing said openings in the damper frame, a base extending down from the lower end of said outer conoidal wall, a. fire box in said base centrally located with respect to said inner conoidal. wall and opening to said ascending passageway, an even within said base and spaced therefrom to leave a passageway therebetween, a smoke fiue communicating with said passageway, and dampers between the fire box and passageway in the base.

at. In a hotel range, an annular top having a plurality of spaced holes therein arranged around the same and lids therefor, an inner wall in the form of an inverted dome, extending down from the inner margin of said top, an outer wall of conoidal form extending down from the outer margin of said top, a division wall between said inner and outer walls forming ascending and descending passageways in the annular space between said inner and outer walls, an annular damper frame extending across said ascending passageway, a base, joined at its upper end to said outer wall, a fire box within said base and located directly below said inner wall, said box opening to said ascending passageway, and a plurality of dampers associated with said damper frame and arranged to close the passage in the ascending passageway, any of said dampers being capable of being swung down to partly open the passageway, whereby the gases arising 10 from the fire box may be directed toward any part of the annular top.
